Indonesia is a signatory of the nuclear Non-Proliferation Treaty (NPT) and has signed but not yet ratified the Comprehensive Test Ban Treaty (CTBT). They are one of the 44 listed countries needed to sign and ratify for the CTBT to enter into force.

They operate three research reactors, the third of them being intended to support the introduction of nuclear power to the country. It is a 30 MW (thermal) unit at the Serpong Nuclear Facility near Jakarta, and started up in 1987.

Indonesia has two established uranium mines. It also has, on a laboratory scale, other front-end capabilities in ore processing, conversion and fuel fabrication. There have been no known experiments in reprocessing, but there is a radioactive waste treatment programme for spent fuel from the research reactors.

Since 1989 Indonesia's atomic energy authority has undertaken a number of feasibility studies and the industry expects tenders to be issued in 2008 once a reactor choice has been made, with construction starting in 2010.
